clavus (uncountable)
From Proto-Italic *klāwos, from Proto-Indo-European *kleh₂w-o-s, from *kleh₂u- (“nail, pin, hook - instruments, of old use for locking doors”). Cognate with Ancient Greek κλείς (kleís, “key”) and Old Church Slavonic ключь (ključĭ, “key”). Latin clāvis (“key”) is either a secondary i-stem derivation, or a loanword from Ancient Greek κληΐς (klēḯs).
